Airtel Retailer — Fraudulent transaction to airtel billdesk

Address:

Kolkata, West Bengal

Today I received a call on my registered mob no. from mobile no.[protected] (Delhi Circle) she said this call from CITI Bank Credit Card Verification Dept. for your card verification she told me my 16 digit card no. [protected] and ask for validity and CVV. I give those info to her after that she said you will get verification OTP and ask me to share with her and I did that after that I found amount Rs.4970 has been debited from my credit card by AIRTEL BILLDESK. Call timing on 14th Feb 2015 afternoon 5.10 PM. From Internet I came to know that this a very common fraud practice of Airtel Money/Billdesk transactions. So I request you to revert the transaction and take necessary action immediately. You may also suggest me to means for reverting the transaction immediately.
